Is this happening on both the desktop and mobile versions of your site, or just on mobile? As well, what theme are you using? Please share a link to your store here so I can take a look for you. Cheers!
I seem to be able to scroll properly on mobile (Safari, iPhone XR) without any issues. Are you still experiencing this problem on your end? Cheers!
I'm having the same issue. On iPhones (no matter which iPhone and which browser) my store won't scroll, unless the user uses two fingers or zooms in. I disabled all popups that I know of but the scrolling issue remains.
Any help appreciated a lot, I had around 10 experts looking at this but nobody could find the cause of this critical problem.
Glad to hear that's sorted for you now! Let me know if you have any more trouble with it.
